Two things to check up-front, from a debugging point of view:
  1. Turn on auto-flush by setting $|=1
  2. Print new-lines after your print statements.
I'm not sure about Win2k, but on Unix, by default, STDOUT is line-buffered, meaning you won't tend to see stuff until the full line is printed, unless you set autoflush on. Either of these changes could allow you to see the text you're looking for.

If we're sure the output is coming out when it should, but your code is somehow not executing, we can begin investigating the module, but realistically, Net::hostent is just a wrapper around gethostbyaddr/gethostbyname.

Update: I am not able to reproduce your behavior as you describe, however, using an IP address that does not resolve back to a name causes my script to die outright: 

Can't call method "name" on an undefined value at test line 8.

Could you be executing this in an eval block or something, which might be trapping the die and allowing your script to continue executing?
